Very new Dell optiplex 755 with Vista Biz + Intel 82566DM-2 Gigabit adaptor
to 100 local home LAN and internet connection. Frequent loss of LAN
connection > red cross > says network cable unplugged (but not). Switched
cables repeatley with old XP PC to eliminate this.

Tested card - OK (this might clear the problem sometimes).

Found a reference to Windows powermanagement but not able to try dissabling
as my Power Management tab differs.

Did not notice untill after I ran Transfer Files & Settings.

The DHCP doesn't assign IP to the computer. Have checked if there is a new
firmware for the router and new driver for NIC? Or check this link.

NIC on latest drive as is the Netgear DG814 router - but this is not shown
as Vista compatable. Just ordered a DG834 (which is). Hopefully this will
help.

Thanks!
 
I am currently experiencing the same problem. So far nothing I have done has
helped. This is the exact same machine and network card and Vista Ultimate.
Currently working with a Linksys SD208 switch, which according to their site
is vista compabitle.

Only similar occurance I have been able to track down on the internet was
someone replacing their NIC to fix the problem. Did your replacing the router
work?
